TV Series

TV Series

In Italian language TV means “TIPO VECCHIO”(old type) because this series of couplings is the first that MB began to produce from 1956 on his own drawings: TV series is well known in Italy and now MB is the only producer of it. These couplings are suitable for any hydraulic application in industry and in agriculture: the hardiness and the wide range of sizes are their peculiar features. The 1.1/4”, 1.1/2” and 2” sizes are also available in brass and in stainless steel AISI 316.

  • Interchangeability: according to MB internal standard
  • Shut-off system: poppet valve
  • Latching system: balls - bearing
  • Connection: pulling back the sleeve
  • Disconnection: pulling back the sleeve
  • Connectability: without pressure
  • Disconnection under pressure: not allowed
  • Threads: BSP
  • Sizes: 1/4" , 3/8", 1/2", 3/4", 1", 1.¼ ", 1.½ ", 2", 2.1/2", 3"
  • Materials: Female in carbon steel, male in high grade carbon steel, induction hardened steel hardened valve
  • Surface treatment: zinc plating and Cr III passivation, springs in C72 steel, high resistance balls 100 C6
  • Seals: standard NBR 85°Shore, on request VITON
  • Antiextrusion rings: only in the 1” size
  • Working Temperatures: NBR -20°C +100°C VITON -15°C +140°C

For temperature exceeding this values, the quick-release couplings will be supplied with all components in steel.
